    "abstract": "We present a new derivation of the expressions for momentum and energy of a\nrelativistic particle. In contrast to the procedures commonly adopted in\ntextbooks, the one suggested here requires only the knowledge of the\ncomposition law for velocities along one spatial dimension, and does not make\nuse of the concept of relativistic mass, or of the formalism of four-vectors.\nThe basic ideas are very general and can be applied also to kinematics\ndifferent from the Newtonian and Einstein ones, in order to construct the\ncorresponding dynamics.",
